Prototype of microprobe (uSonda) is a small built-in device intended for use in smaller ISP (Internet Service Provider), or directly into the infrastructure between the ISP and the end user for interception of communication. This final prototype is based on the hardware platform ZE7000 with the powerful chip Xilinx Zynq (ARM + FPGA). Prototype also consists of a specific firmware and software stored on the SD card. Prototyp also consist of documentation.
